Precipitation - radar/gauge 5 minute real-time accumulations over the Netherlands

Gridded files of radar-derived 5 minute precipitation accumulations, corrected by rain gauge data. Radar data from 1500 m over the Netherlands and surrounding area measured by Dutch, Belgian, and German radars are corrected by available data from automatic rain gauges. Time interval is 5 minutes. Files in this data set are for the previous 24 hours. See data set nl_rdr_data_rtcor_5m_tar/1.0 for an archive.

Linage statement Radar reflectivities are measured by radars in the Netherlands, Belgium, and Germany. Single images per radar at 1500 m height are generated by linearly interpolating radar reflectivities in altitude. Radar reflectivities are then converted to rainfall intensities by using the Z=200R^1.6 formula. A mean bias correction factor is derived based on the most recent 1 hour rainfall accumulations from automatic rain gauges. The resulting radar rainfall estimates from all radars are then combined to a single product by taking a weighted average. The weigths are a function of the distance of a given point to the radar.
